The stove will supply around 7-8kw to the boiler and 4-5kw directly to the room. 

To calculate your heating requirements - An 8kw boiler equates to around 28,000 BTU (1kw = approx 3500 BTU.) - Your radiators will be measured in BTU. To calculate your requirements add up all of the BTU.s of each radiator in the house.

The stove includes an additional thermostat that automatically opens and closes an additonal vent on the stove. This probe is linked directly to the boiler and opens when the stove requires extra air and closes if the boiler gets too hot.

Suitable for open vented systems, The boiler has 4 x 1" threaded outlets at the rear. This stove has the required CE,BSEN data plates on the back. The stove is also over 75% efficient, this means HUGE savings on fuel bills.

The Ottawa has an advanced secondary clean burn system that is controlled by a chrome pull leaver on the base of the stove. This leaver opens and closes a vent that pulls air over the fire, re burning the initial smoke emitted by the stove. This makes the stove a lot more efficient and eco friendly saving you a large amount in fuel costs.
